I have a 45L Engel that I brought over from Australia. Tested it about 3 month ago and it still seems to work. Its a 240V AC and 12 Volt DC variety.
I'm not using it. Where do you live?
I'm in AZ, and unless a certain family member in Gig Harbor is heading down this way anytime soon, shipping may kill the deal.
Nikos, as far as quality goes, the Norcold Tek II that I bought is the exact same as the older ARB models, and the Engels...no difference whatsoever. I've never used, or will use a 12V cooler. I've had great reliability out of my old Engels, both in 45 and 60 flavor, and not so great out of a Waeco. That is why I'm looking for another Engel/Norcold variant. When I bought my Engel originally, is was slightly above $600 for it, so to me $400 is a fair deal for a working fridge.
Finally, as it turned out, it wasn't the power supply at all. It was the 12V DC cord that was bad. Plugged in another 12V cord from a friend, and voila!
